> Main ingredient of all paper is plant material. Loading or filling material such as clay, CaCO3, Talc, TiO2 etc. are used for higher brightness and better printability. Rosin, alum or combination of other chemicals is used to make paper water resistant.
I guess the book I mentioned just categorised things differently - I think the "glue" bit was mainly about water resistance and general durability. Then again, it's been years since I've read the book (and I don't have it with me to check it right now), so I might be misremembering it.
Either way, I admit that "chemical additives" would make more sense as a general label! I mean, adding a chemical to make paper fire resistance can't be called filler or glue.
